To all whom z'tmay concern: 1

'Be it known that I, JAMES XV. KNoBLooK, a citizen of the United States, and residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Portable Sea-rchlights, of which-the following is a full and clear specification. v

This invention relates more especially to portable searchlights in which provision is made to render such searchlights proof against the undesirable effects of water, smoke, dirt etc. The primary object of my invention is to provide improved means for adapting a Searchlight to transmit telegraphic signals. Other and further objects will appear in the specification and be pointed out in the claims, reference being had to the accompanying drawings which exemplify my invention in a preferred embodi- In I the drawings Figure 1 isa side elevation of a portable Searchlight provided with my improve ments;

Fig. 2 is a top plan view of the same;

Fig. 3 is a top plan view on an enlarged scale of the telegraphic key lever housing and key lever, said-housing being partly broken away;

Fig. 4 is a side elevation on an enlarged scale, of the upper right hand portion of Fig. 1, parts being broken away;

Fig. -5 is a front elevation on an enlarged scale, of the telegraphic key and operating connections Fig.6 is a wiring diagram.

Referring more particularly'to the drawings, in the embodiment shown-therein, the handle 1 is suitably connected to a sheet metal housing 2 provided with a transverse partition 3 forming a battery chamber between it and the rear wall ,4 of the housing. The battery chamber isprovided with a raised bottom 5 for supporting a storage battery it suitable elevation .to be connected up to the sockets to be hereinafter referred to. A reflector housing 6 is journaled on an axis 7, so that light from a lamp 8 (see Fig. 2) provided with a reflector 9, may be made to project light in any desired direction. The battery chamber is provided with a closure 10 which is hinged at 11 to the rear wall 4. Surmounting the closure .10

is a telegraphic key lever housing comprising portions '12, 13an-d l4,'portion 12 being rigidly mounted on the closure 10 and pro'- by' means of which it may be oscillated for sending telegraphic signals. Conductor bars-19 and 20 may be connected respectively to key lever 16 and a conductor 21 which leads to the lower contact22 of this telegraphic instrument. Condu-ctor bars 19 and 20tern1inate respectively in knife blade contacts 23 and 24. As shown in Fig. 5, the knife; blades 23 and 24 cooperate respectively with the spring contacts 25 and26 provided below with bindingposts 27 (see Fig. 4).

Referring to-Fig. 6, the battery 28 .has its terminals 29 and 30 connected respectively to'lead wires 31 and 32, the former of which connects to one terminal 33 of a lamp 34. The otherterminal 35 of said-lampfis connected by a wire 36 to a wire 37' which is connected at one end to .oneiof the binding posts" 27. In the diagramshown in Fig. 6',

thebinding posts 27 are represented asconnee-ted directly to the key lever 16 and-conductor 21 respectively, the interposed conductors being omitted in this diagram. The wire 37 is connected at its other end to'one of the terminals 38 of a switch 39, the other terminal 40 of which is conneoted'to-"a wire 41 leading to the other bindingpost 27,- referredtoabove. Wire 32: from the battery 28connects with this wire 41 making the circuit connections, as shown in Fig.6. The wires 31 and 32 leading from the battery ter minals may "be conducted through suitable sockets 43 and .44. Wires 3? and 41 leading from the binding posts 27, 27*to, the termi nals 38 and 40 of the hand switch 39, may be conducted through suitable sockets 45 and 46, the connections between wires 32 and '41 and wires 36 and 37 being made as shown in with the spring switches 25 and 26 with which they cooperate.

The advantages of my improved construction will now be readily understood and briefly related are as follows:

In placesaexposed to water, smoke, dirt, or other undesirable conditions, suclr as may be met with at a fire, for example, a

portable searchlight of the general character shown in outline in Figs. 1 and 2, is of great service. It becomes necessary, however, to protect the various parts connected with such a device from the smoke, water, dirt, etc. The details of construction of the Searchlight proper shown in Figs. 1 and 2 are shown, described and claimed in my copending application, filed February 9, 1917, Serial Number 14:7,603. The present application shows an improved construction adapting it to be operated by a telegraphic instrument mounted directly on the searchlight, and in which the several parts are fully protected against the water, dirt, smoke, etc. Thus, should it be desired to use this instrument to flash signals of light, the extension 14. of the telegraph lever housing may be swung on its hinge 16 to make the finger grip 18 accessible for flashing the light signals. During this operation, hand switch 39 is, of course open, so that the electric circuit is periodically completed through the lever 16 and conductor 21. lVhen it is necessary to gain access to the sending apparatus, the closure may be swung about its hinge 15 to open up the housing 12. In order to adapt this telegraphic apparatus to be mounted directly upon the closure 10 of the battery chamber, the knife bladeswitches 23 and 24k carried by the telegraphic apparatus, are made to cooperate with the spring contacts 25 and 26 mounted on the housing 2. The battery chamber may therefore be opened and closed at will. At the same time, the steady light circuit may be utilized by closing the switch 39 whether the battery chamber is open or closed.

2. In a portable searchlight, a lamp, a storage battery, a housing for said storage battery provided with a movable closure, a telegraph key mounted on said closure, an energizing circuit for said lamp, including said storage battery and said telegraph key, said circuit being provided with contacts opened and closed by the movement of said closure, and a housing fO1.S2LiCl telegraph key mounted on the closure for said battery housing.

3. In a portable searchlight, a lamp, a storage battery, a housing for said storage battery provided with a movable closure,

a telegraph key mounted on said closure,

.an energizing circuit for said lamp, including said storage battery and said telegraph key, said circuit being provided w1th contacts opened and closed by the movementof said closure, and a telegraph key housing comprising a main body mounted on the battery housing closure and an extension hinged to said main body, said hinge being arranged on an aXis parallel to the pivotal axis of the key lever.

5. In a portable searchlight, a lamp, a storage battery, means for housing said lamp and storage battery, a telegraph key lever provided with a finger pad, and a housing for said key lever having a hinged portion for uncovering only said finger pad, said key lover housing being provided with a hinged closure to which said hinged portion is pivotally connected.

(3. I11 a portable searchlight, a lamp, a storage battery, means for housing said lamp and storage battery, a telegraph key lever provided with a finger pad, and a housing for said key lever having a hinged portion for uncovering only said finger pad, said means for housing the lamp and storage battery including a separate chamber for the. battery having a closure to which said key lever housing is hinged.
